error with usage of Liaison_elem option

Dear all,
My name is karthick. I am new to the code_aster and I using it for last couple of weeks. I made a FEM model, consist of two parallel plate connected by a rivet for Linear Static Analysis. When I run the analysis it gives error. I used Liasion_elem-->2D_Pou for connecting the 2d element edges to the 1D element node. I attached the model file. please help my to resolve to issue.

Thanks in advance for sparing your valuable time.

Best regards
Karthick Srinivasan

Re: error with usage of Liaison_elem option

I didn't check your model in detail and hence do not have clear idea of what you are trying to achieve. Yet, I could see a few issues.

You have POUTRE and COQUE elements. In LIAISON_ELEM you are using 2D_POU option. As per documentation, this option requires 2D part to be meshed quadratic.

Probably what you need is COQ_POU option.
